Taking Krill Oil
is an outstanding way to supplement with omega-3 fatty acids. Krill oil not only contains omega-3 fatty acids, but also the potent antioxidant, astaxanthin. Amazingly enough, Astaxanthin helps to decrease the expression of the enzyme, 5-alpha reductase, which catalyzes testosterone into the dreaded DHT (Dihydrotestosterone).
However, there are far more reasons to supplement on Krill Oil...for one, it helps to suppress an inflammatory prostaglandin called interleukin 6 in response to DHT.
Abundant evidence exists suggesting that prostaglandins can affect the growth of human hair follicles. Prostaglandins are hormone-like molecules that affect inflammation and other necessary processes in the body. The hair follicle cells in balding scalps upregulate (increase) the prostaglandin interleukin 6 (IL-6). Interleukin 6 suppresses hair growth by affecting the growth stages (cell proliferation) of hair follicles. 
Interleukin 6 is signaled by balding dermal papilla cells, while silent in non-balding cells. Too much IL-6 shortens the growth stages (anagen) and prolongs the sleeping stages (catagen).
In a recent study, medical students were assigned either omega-3 fatty acid supplements or placebo. They were observed for a year to evaluate their stress levels. It was found that those students who received omega 3 fatty acids had a 14% decrease in lipopolysaccharide (LPS) stimulated interleukin 6 (IL-6) production and a 20% reduction in anxiety symptoms when compared to the placebo group. 
Two of the biggest issues with supplementing on Fish Oil or some other well-known form of Omega-3 supplement include rancidity and low bioavailability (poor absorption). The naturally-occurring Astaxanthin in Krill Oil acts as a natural preservative, preventing Krill Oil from becoming rancid. Standard fish oil is not afforded this luxury, and most products are, as a result, rancid and worthless. Additionally, the omega-3 fatty acids within Krill Oil are bound to phospholipids that assist these acids in permeating through the membranes of our cells. Unfortunately, Fish Oil lacks phospholipids, resulting in a far lower bioavailability. We endorse and recommend Ortho Nutrition's Antarctic Krill Oil
as a healthy source of bioavailable omega-3 fatty acids.
